Earlier returns list fewer of these outlets, so totals are not comparable between years. The median per outlet and the like-for-like change are fairer comparisons. Counts are events, not volume.

Questions about Anglian Water

What do the Anglian Water figures cover?
This page totals 1,438 outlet records with a usable 2025 spill count, out of 1,442 records in the England dataset. Missing values are not counted as zero.
How many Anglian Water outlets are linked to a live feed?
1,398 records are matched to a monitor in the company live feed. A link does not mean the monitor is working now. Use the status filters above to see the latest report and its date. 44 records have annual figures only.
How many Anglian Water outlets recorded zero spills in 2025?
244 records report zero counted spills. 119 records have monitor operation below 90%, so a zero from one of those outlets may not cover the whole year.
Does a recorded spill show how much sewage was discharged?
No. Event duration monitors report when an overflow operated. They do not measure the volume released or the water quality.
Can I compare Anglian Water with another company?
Take care. 119 records have monitor operation below 90%, and companies differ in outlet numbers and area. Check missing values and monitor coverage before making a comparison.
How do I report pollution from a Anglian Water outlet?
Use the official pollution reporting route in our guide. Give the outlet name, permit reference and the time you saw the problem. Sewage Map does not send incident reports.
